Heater FAQ’s:
Q: What is a flame failure protection device?
A: If the pilot flame dies, the thermocouple system will cool down instantly. The
sensor will close the electromagnetic valve cutting the gas flow off. This will stop
the gas from flowing through the system, turning the heater off.
Q: What is infrared heating?
A: Infrared heating systems refer to pieces of equipment or appliances that are
placed inside a space to provide heating. Heating occurs due to radiation heat
transfer. Radiation heat transfer is the exchange of thermal energy between two
or more bodies.
The ceramic panels create infrared heating, heating objects around the heater
as well as the air (convection heating).
Q: What is a positive off switch?
A: A positive off switch enables the
user to switch the appliance off without
having to close the valve on the cylinder
(like a stove or BBQ).
Q: What is an ODS (Oxygen Depletion Sensor)?
A: A safety device that activates the heaters’ monitoring device in case
excessive levels of CO² (carbon monoxide), are detected. Continuous burning
reduces the levels of oxygen, causing the pilot flame to become unstable and lift
off the thermocouple (flame failure protection device) tip. The appliance then
turns off automatically long before the situation becomes dangerous.
Heater FAQ’s: (continued...)
Q: What effects do separate burner chambers have on a heater?
A: On older heater models all three ceramic panels were mounted on a single
burner chamber. This allowed gas to “drift” to non-burning panels and escape
through it, allowing a slight increase in the gas smell and the wasting of fuel. The
new generation of heaters have 3 independent gas chambers. This prevents the
gas from floating to unused panels and thus reduces gas emission odours.
Q: How long is the heater supposed to burn for?
A: Refer to your instruction manual or technical data sticker on the back of your
heater. It will supply the g/h (grams per hour)consumption. Take the weight of
your gas cylinder e.g. (9kg = 9000g) and divide it by the g/h of your appliance.
The total you get will be the maximum amount of hours the appliance will be
able to burn for. (eg. 9000g / 265g/h = 34hrs at max)
Q: Can a cylinder be overfilled?
A: Yes. Cylinders should only be filled to 80% of the
cylinder capacity. This allows for gas expansion/
vaporization in the remaining 20% space.
If the cylinder is filled to the top, and then warmed, the
liquid will expand and the cylinder can burst open. This
is very dangerous and could cause serious damage and
probable injury. It should therefore be kept away from
extreme heat. Over-filling also causes issues with a gas
appliance not functioning correctly as liquid gas is being
pumped into the regulator, blocking it up.
Q: Can I see if the cylinder is over-filled?
A: The cylinder neck contains information on the weight of the cylinder. The
tare weight (TW) is the weight of an empty cylinder. Add the tare weight to the
capacity of the cylinder (e.g. TW – 9.4 and capacity 9 = 18.4kg) and weigh it. If
it exceeds the total weight, then your unit is over-filled. In such an instance, the
cylinder must be returned to the re-filling station. Users are no longer allowed to
purge the excess gas themselves.
GAS CYLINDER:
A 9kg ALVA gas cylinder
A 9kg ALVA gas cylinder with a 5/8 inch BSP left hand thread is recommended.
This matches the supplied regulator.
Cylinders must be stored in an upright position, in a well v entilated and damp free area and out of reach of children.
The cylinder must never be stored where temperatures can
reach or exceed 50’C.
DO NOT store the cylinder near open flames, pilot lights or
any other sources of ignition.
DO NOT SMOKE WHILE HANDLING THE CYLINDER.
Heater Set Up:
This heater makes use of an industrial cylinder (9kg
cylinder recommended) with a 5/8” BSP thread; horizontal
exit valve. The Bullnose regulator
supplied with the heater tightens to the left hand side
(anti-clockwise). (Figure A)
If you have bought a new gas cylinder, the cylinder needs
to be purged (cleared out), before it’s first use. If it is not
Fig.A
purged of air, the heater will not work properly. This should
happen at the gas filling station when you fill up the cylinder. Always check this
with your gas supplier.
1. Advise customers to be sure that this is
the product they need before opening
and removing the heater from the
packaging.
2. Assemble the unit.
3. Check if the nose cone is present, secure
and in good condition. (Figure B)
Fig.B
1. The regulator goes directly
into the cylinder valve. Always
make sure the regulator
bottoms fully. The use of any
adaptors is illegal.
2. Screw the regulator into the
cylinder valve. DO NOT use a
tool to tighten the regulator; it
is to be hand-tightened only.

Fig.D
3. Open the control valve 1½ turns
to the left (anti-clockwise).
(Figure C)
4. Push the control knob down for at least
10 seconds, but DO NOT try to ignite the
heater. This will allow gas to flow through
the heater,making the leak test possible.
5. DO THE LEAK TEST (see next page)
6. Place the cylinder in the heater cabinet
by securing the rear guard in place.
(Figure D)

Leak Test:
The leak test must be carried out in a well-ventilated area, free from any flames
or other sources of ignition.

1. With the cylinder connected to the heater. Open
the cylinder valve.
2. Brush the connections (heater to cylinder) with a
solution of equal parts soap and water (make sure
it’s foamy).
3. A stream of bubbles forming indicates a gas leak.
(See Fig.F)
4. If bubbles appear, turn the cylinder valve OFF
(clockwise) and disconnect the heater from the
gas cylinder.
5. Tighten the connection and retry the leak test.

6. If you are unsure or if you cannot tighten the
connection, place the cylinder outside in a cool,
well-ventilated area and contact ALVA on 086 100
(ALVA) 2582.
7. A leak between the heater and cylinder can lead
to a high pressure fire, which is very dangerous
and can result in extensive injury or even death.
Using The Heater:
1. This heater can be regulated to three
different heat selections:
“ LOW” “ MED” and “ HIGH”
2. Open the cylinder valve by turning the cylinder
valve to the left.
3. Press the control knob down at the “ OFF”
position. Hold the control knob down for ±10-15
seconds.

This heater must be turned
off using the control knob
first (Figure G) and only then
closing the cylinder valve.
4. While holding it down, turn the control knob
anti-clockwise to Ignite/Low. The heater should
make a click sound and you should see a
spark. The pilot flame should ignite. Once the
pilot flame ignites hold down the knob for
another 10-15 seconds.
5. Repeat step 3 if the pilot flame does not stay
lit. This may require more than one attempt.
Once the pilot flame and centre panel are

2. The heater should be checked once a year by a
qualified technician.
3. If faults are suspected or detected, stop using the
heater and contact ALVA.
4. Clean the exterior and storage area of the heater
when required to remove dust and prevent lint build
up.
5. DO NOT use abrasive products to clean the heater;
these may damage the paint work.
6. While in operation the pilot flame should be steady. If
it flickers or is yellow the heater needs to be serviced.
(Fig.I)
If any part of the heater is in need of replacing, use only
original parts. Using any other spare parts is dangerous
and will void the warranty.
When the heater is not going to be used for an extended period of time, keep it
covered or in its box, to prevent dust from settling on the panels. When removing
the heater from storage, use a vacuum cleaner to vacuum the panels before reuse.
